Answer
Photosynthesis
Explanation
The sun keeps the carbon cycle working by providing light energy. This light energy is used to carry out a process called photosynthesis by organisms that are known as producers. This process creates organic matter from carbon dioxide and water. Photosynthesis thus helps maintain the activity of carbon sinks.
D) decreasing blood viscosity as blood will be lighter and easily movable hence an increase in blood flow
To have a holiday for the earth and that everyone should take care of it as it is a yearly reminder to take care of earth
Ans.
Errors that occur during DNA replication lead to mutations, which represent permanent, heritable changes in genetic material. These errors can pass from parent cell to daughter cells and affect many generations of cells.
On the other hands, errors that occur during protein synthesis lead to formation of defected or non-functional protein. These errors cannot pass from one cell to another and affect only one cell, which requires that protein for its proper functioning.
Thus, 'it is more important to check errors during DNA replication that errors during protein synthesis.'
The answer is B and C.
B is correct because the R represents smooth seeds. It is dominant because the trait is represented by a CAPITAL letter. In a genotype, the capital letter means that the trait is dominant.
C is correct because the F1 generation are considered hybrid because of their heterozygous trait, which also means hybrid trait. You can tell based on the genotype as well. The results show Rr combination. If the resulting trait is represented by both capital and lower case letter of a specific trait, then the trait is called a heterozgous or hybrid trait.
